Question

question #2

Answer 1

You need to know the formula for Surface Area for a cylinder

\( A=2\pi rh+2\pi r^2\)

where r is your radius and h is the height

Answer 2

Remember that the radius is half the diameter

so if your diameter is 30, then what is your radius?

what is half of 30?

Answer 3

15

Answer 4

So that's your radius

and you have a height of 72 in

So plug it into the formula and solve

\( A=2\pi rh+2\pi r^2\)

\( A=2\pi(15)(72)+2\pi (15)^2\)

just multiply and add

Answer 5

so 8199.56?

Answer 6

That's correct

Answer 7

Thanks

Answer 8
